When my SQL query begins with INSERT INTO and I select (highlight) the entire text of the query before pressing F9, the progress bar freezes at the bottom of the screen and in the “Background Processes” window, and the editor tab says “50%”, until the query eventually finishes. It looks like the query is stuck, and it is misleading for the tab to say 50% when it is nowhere near half done.
